Narrative Summary of New Rule or Rule Changes: New Rule Amended Rule 

 Rule 466 requires general cleaning to be performed by materials that contain less than 50 grams per liter VOCs 

as applied. The rule also includes other requirements for cleaning electrical and electronic apparatus 

components, architectural application equipment, and adhesive application equipment. The VOC limit varies 

depending on the equipment being cleaned. The rule allows the use of air pollution control equipment or an 

airtight or airless cleaning system as alternatives to complying with the VOC limits in the rule. The rule also 

specifies cleaning method requirements, general equipment requirements, operating requirements, storage and 

disposal requirements, and recordkeeping requirements 

Pollutant(s) Regulated by the Rule (Check): ROG (NOx) SO2 

 (CO) PM TAC (name): 

II. EFFECT ON EMISSIONS

Complete this section ONLY for rules that, when implemented, will result in quantifiable changes in emissions. Attach reference(s) for emission factor(s) 

and other information. Attach calculation sheet showing how the emission information provided below was determined. 

Net Effect on Emissions: Increase Decrease N/A 

Emission Reduction Commitment in SIP for this Source Category: The 1994 SIP included a commitment to reduce VOC 

emissions from surface preparation and cleanup solvents by 2.9 tpd from the Sacramento district. Surface 

preparation and cleanup solvents are included in multiple rules. The adoption of Rule 466, together with 

amendments to Rule 454 (Degreasing) achieved a reduction in VOC emissions of 1.3 tpd, bringing the total emission 

reductions for this source category to 2.5 tpd in the Sacramento district.

Inventory Year Used to Calculate Changes in Emissions: 2002 Area Affected: Sacramento County

Baseline Inventory in the SIP for the Control Measure: 5.6 tpd for the Sacramento district.

Emissions Reduction Commitment in the SIP for the Control Measure: 2.9 tpd for the Sacramento district.

Revised Baseline Inventory (if any): N/A

Revised Emission Reduction Estimate (if developed): N/A

Note that the district’s input to the Rule Evaluation Form will not be used as input to the ARB’s emission forecasting and 

planning. 

III. SOURCES/ATTAINMENT STATUS

District is: Attainment Nonattainment Split 

Approximate Total Number of Small (<100 TPY) Sources Affected by this Amendment: 3750

Percent in Nonattainment Area: 100% 

Number of Large (> 100 TPY) Sources Controlled: 0 Percent in Nonattainment Area: N/A% 

Name(s) and Location(s) (city and county) of Large (> 100 TPY) Sources Controlled by Rule (Attach additional sheets as 

necessary): N/A

IV. EMISSION REDUCTION TECHNOLOGY

Does the Rule Include Emission Limits that are Continuous? Yes No 

If Yes, Those Limits are in Section(s) 301 of the Rule. 

Other Methods in the Rule for Achieving Emission Reductions are: listed in Section 304. Section 304 is an alternative to 

complying with emission standards in Section 301 by using air pollution control equipment with a control device efficiency 

of at least 95% and a collection efficiency of at least 90%. 

V. OTHER REQUIREMENTS

The Rule Contains: 

Emission Limits in Section(s): 301 Work Practice Standards in Section(s): 302-303

Recordkeeping Requirements in Section(s): 501 Reporting Requirements in Section(s): N/A
